- Add escHtml alias (lt.escHtml) to both pages so existing template strings work without touching 40+ call sites - Replace raw fetch() with lt.api.get/post in loadInspector, loadLinks, runDiagnostic, pollDiagnostic - Replace setInterval(load*, 60000) with lt.autoRefresh.start() for intelligent polling - Add lt.toast.error() to catch blocks for user-visible error feedback Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
